I don't even know why I have tinnitus. It's not end of the world bad tinnitus, but sometimes does get a little annoying. It is louder in the evenings/nights than in the mornings. I have it since primary school 4th grade or so, when I realized I have it, because an old teacher described her own tinnitus. But as far as I can remember there was no very loud sound event before that causing the tinnitus. Maybe it comes from bad posture or so, already in primary school. Too heavy school bag with too many books? Who knows. Have had it ever since. Most effective masking method for me is sound of rain whitenoise like that rainymood website.
